通过对长春第一育苗场普查得出,长春市第一育苗场共有苗木26科45属72种,其中针叶树12种,阔叶树37种,花灌木23种。同时,分析了苗木的株数结构、胸径结构和高度结构,提出了苗圃生产的改进建议,以期为长春市第一育苗场的苗木生产和规划提供理论依据。
Through a survey on seeding in No. 1 Cuhivation Farm of Changchun City, we know that there are 26 family, 45 genus and 72 species, including 12 species of conifer, 37 species of broadleaved tree and 23 species of flowering shrub. This paper analyzes the tree number structure, DBH structure and height structure of seeding and gives some suggestions on the improvement of seeding produ- cing, hoping to provide theoretical references for the seeding producing and planning in No. 1 Cultivation Farm of Changchun City.
